WILLIAM A. PHILLIPS, OF FORT KEOGH, ASSIGNOR OF ONE-HALF 'lO THOMAS J.PORTER, OF MILES CITY, MONTANA.

CARPET-STRETCH ER.

SPECIFICATION forming part of Letters Patent No. 510,361, dated December5, 1893.

Application filed May 29, 1893.

To all whom it may concern.-

Be it known that 1, WILLIAM A. PHILLIPS, second lieutenant,Twenty-Second Infantry, United States Army, a citizen of the UnitedStates, residing at Fort Keogh, in the county of Custer and State ofMontana, have invented certain new and useful Improvements inCarpet-Stretchers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Figure 1, is a perspective view of this device as in use one of thelevers raised. Fig. 2, is a sectional view on a line between the levers.Fig. 3, is a detail in elevation of one of the levers. Fig. 4,showsadetail side view of the carpet stretcher in use on astair. Fig. 5, is adetail in bottom plan of main frame and saw tooth plate.

This device belongs to that class known as carpet stretchers.

The novelty in this invention consists in the construction of theseveral parts and in their combination with each other and inthe deviceas a whole all as will be more fully described as well as pointed out inthe claims.

vIn the drawings A, denotes the main frame one end a, of which isslightly inclined upward, and under this and at right angles with it issecured by rivets R, the plate B, having on its front edge the saw teethb, pointing inwardly. The opposite and upwardlyinclined end of the frameis slotted at a, and to each 35 end of the point 0?, thus formed isfastened the generally vertical brad O, the lower end c, of which ispointed and curved slightly inward. In the slot a, the lever claws D,are pivoted by the pin 0, which is secured at its ends in the two brads,and passes through the slot (1, in each claw. Each claw is extended to apoint nearly over the plate B, and has at its end a handle at. As thusmade the deviceis put into use by engaging the teeth b, into the carpetnear its edge. Then by turns the end 6?, of each lever claw D, ispressed down into the wood of the floor and on the upward and gentlemovement of the handle of the claw a very strong pull is made on thecarpet; at this moment the carpet is held securely in Serial No.475,913. (No model.)

place with one lever claw till the other, lever claw is in like manneras the first lever claw is now operated; thus in turns first by one handand then by the other, each claw lever is alternately operated pullingthe carpet up by steps in the walking movement of the two lever clawsuntil the carpet is up to the desired point Where it is held securely bytapping lightly with a hammer on the hammer heads 0 driving the brad end0, into the 6:; floor. It will be observed that the hammer heads 0 ofthe brads which project considerably above the main plate A, act asguides for the claw levers when'they are moved. The amount of leverageof the claw is regulated by the position of the pin 0, in the slot; thusthe point of the lever claw can be placed considerably in advance of thepoints of the brads;

or the point can be drawnin so that in its movements the point will fallinside of the brads. This feature of extensible lever claws andchangeability of the fulcrum pointis of very great value as it insuresthe most perfect results under all circumstances of use. It isparticularly to be noted that with the two le- 7 5 vers, one lever isused to hold the carpet in place while the other is being engaged totake another step forward with the carpet. This prevents the necessityofdriving the brad ends into the floor each timea forward move- 50 ment ofthe carpet is ended. When the carpet is up as far as is necessary thenthe brad ends are driven into the floor beside the mop board or near thewall. This double action is of great importance as it makes theoperation of walking up the carpet to its position by steps very rapidand does away with the necessity of injuring the floor by having thebrad ends driven in the floorat each forward movement of the carpet.Each of the rivets B, may be extended below or beyond the saw toothplate in the form of a spike B. This is of value when it is necessary touse the stretcher on top of the carpet as in stretching a stair carpet.See Fig. 4. It will also be par- 5 ticularly noted that the claw leversarenpivoted directly to' the end of the main frame and that there are nolinks or other costly and easily broken connections between the frameand levers.

This device can be made of metal and in such single pieces asmay combinethe saw tooth plate, the main frame and the brads in one; but in thisdetail of manufacture and of material used, I do not propose to limitmyself in the least to adopt such varieties in structure, form and makeup, while preservin the essentially novel features above described asmechanical skill may suggest.

What I claim is 1. The main frame having at one end, the inclined sawtooth plate and the upwardly inclined and slotted opposite end, thevertical brads fixed thereto and the ends of the claw levers pivoted tooperate between, said brads, the several parts constructed and combined,substantially as described.

2. In a carpet stretcher, substantially as described, the combination.with the main frame and the saw tooth at one end of it, the lever claws,each slotted near the end, and pivoted in the opposite end of the frame,whereby an alternate drawing on the carpet can be effected.

3. In combination with the main frame A, having theinclined saw toothplate B, at one end, the brads O, secured to the opposite slotted endsof said plate, and the lever claws D, adjustably pivoted between saidbrads where by, an alternate movement of each lever claw may beobtained.

4. The carpet stretcher as above described, the main framehaving teethat one end, and at the slotted opposite end the brads pointed at theirlower ends, and having hammer heads projecting above the slotted end ofthe main plate and the claw levers pivoted between said brads and bythem guided in their movements, all substantially as described.

5. In combination with the main frame and the levers pivoted in itsslotted end and the brads attached to said end, the saw tooth plate andthe rivets securing same to the main frame, said rivets havingprojecting and spike ends, substantially as described.

In testimony WhereofIaifix mysignaturcin presence of two Witnesses.
